The AbinitioDA Project v1.0: Non-local correlations beyond and susceptibilities within dynamical mean-field theory
Anna Galler, Patrik Thunström, Josef Kaufmann +3
The ab initio extension of the dynamical vertex approximation (DA) method allows for realistic materials calculations that include non-local correlations beyond and dynamic…
Towards ab initio calculations with the dynamical vertex approximation
A. Galler, J. Kaufmann, P. Gunacker +3
While key effects of the many-body problem---such as Kondo and Mott physics---can be understood in terms of on-site correlations, non-local fluctuations of charge, spin, and pairin…
Continuous-time quantum Monte Carlo calculation of multi-orbital vertex asymptotics
Josef Kaufmann, Patrik Gunacker, Karsten Held
We derive the equations for calculating the high-frequency asymptotics of the local two-particle vertex function for a multi-orbital impurity model. These relate the asymptotics fo…
